General Cable, a world leader in the cable sector, has recently issued a catalogue of high and extra-high voltage cables of up to 500 kV. The catalogue, which is published in English and includes 56 full-colour pages, abundantly illustrated with graphics and photos, is an extremely useful tool for electrical sector professionals and provides the know-how necessary to make calculations and establish dimensions in these cable types. There are, moreover, very few cable manufacturers whose ranges include systems of extra-high voltage cables with a maximum voltage of 550 kV.
